ISAAC DE FORD, OF FOREST CITY, MISSOURI.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 713,407, dated November11, 1902.

I Application filed June 2, 1902. Serial No.110j002. (No model.)

T0 all whom it may concern.:

Beit known that I, ISAAC DE FORD, a citizen of the United States,residing at Forest City, in the county of Holt and State of Missouri,have invented a new and useful Vise- Wrench, of which the following is aspecification.

My invention relates to wrenches; and the object of the same is todesign an adjustable wrench which will be simple in construction andefficient in operation.

The novel construction employed by me in carrying out my invention isfully described in this specification and claimed, and illustrated inthe accompanying drawings, forming a part thereof, in which- Figure l isa side elevation of my wrench.

Fig. 2 is a longitudinal section of the same.

Like numerals of reference designate like parts in the different viewsof the drawings.

The numeral l designates the body of my wrench, which has a jaw 2 formedintegral therewith, which I shall term the outer stationary jaw, whichjaw extends at right angles to the body, which is uniform incrosssection. Mounted in contact with the front of the body 1 is asliding bar 3, having an enlarged head 4: on one end, which head isserrated to form a gripping-jaw 5, located to cooperate with the jaw 2to grip a nut. A clip 6 is secured to the bar 3 and embraces the body l,and thereby serves as a guide. A clip 7 is connected to the lower end ofthe body l and embraces the lower end of the bar 3 to serve as a guideand also as a hand-grip in operating the tool. The end of the slidingbar 3 is reduced and threaded to form a screw S, which is engaged by aninternally-threaded cylinder 9, connected by a neck l0 to a knurledadjusting-nut 1l. The cylinder 9 ts snugly in notches 12 and 13, formedin the body l and clip 7, while the neck 10 is engaged by the clip 7. Bythis arrangement the nut Il is held against all longitudinal movement. Atransverse aperture l1a is formed in the nut to enable it to be turnedby a key. V

To adjust my wrench for nuts of different sizes, the nut 10 is turned bythe fingers or by a key. The location ofthe nut renders the turning ofit very easy, since it extends beyond the end of the wrench and may berevolved continuously with a key without the necessity of letting go totake a new hold, as is always necessary when the nut is located withinan aperture or parallel to another member.

I do not wish to be limited as to details of construction, as these maybe modified in many particulars without departing from the spirit of myinvention.

Having described my invention, what I claim asnew, and'wish to secure byLetters Patent, is-

In a wrench, the combination of a body having a jaw on one end, aslidingly-mounted bar bearing a jaw on one end located to coperate withsaid first-mentioned jaw, the other end of said bar being'reduced toform an adjusting-screw, a clip connected to said sliding bar andembracing said body, a clip connected to said body and embracing saidsliding bar, and an adj usting-nut having a cylindrical portionconnected thereto by a neck, said cylindrical portion fitting in a notchin said clip with said nut projecting beyond the end of the said body,substantially as described.
